PURPOSE:To repair the steel tapping hole in a short time with good workability by using a jig obtained by fixing a truncated conical refractory ring to a long- sized pipe on its periphery at the outer end of a converter. CONSTITUTION:A jig 1 obtained by fixing a truncated conical refractory ring 3 to a long-sized iron pipe 2 having almost the same diameter as the reference original diameter of a steel tapping hole on its periphery at the outer end of the converter is used. The jig 1 is inserted into the steel tapping hole 6 of the converter 10 from the tip of the pipe 2. A castable refractory is gunned on the periphery of the abutting part between the ring 3 and the hole 6 to form a sealing part 10. The converter 5 is then horizontally laid, and the castable refractory is gunned between the pipe 2 and the lining refractory 13 of the hole 6 from a feed pipe 15 to fill the gap with the castable refractory. The refractories are then dried, and the hole 6 is repaired.
